What is Probiotics for dogs?

Probiotics for dogs are simply good and beneficial bacteria that are mainly found in the gastrointestinal tract. Humans and animals including dogs have these bacteria in their millions and they help in digestion, improving the immune system and immune function, countering bad bacteria among many other benefits.

The microbiome is a term that is used to refer to all the microorganisms that live within vertebrate animals and this includes probiotics.

A dog will therefore require a healthy microbiome for proper food digestion and to keep his immunity strong.

Dog’s probiotics are similar to the good bacteria found naturally in your dog’s digestive tract. Some of these bacteria include the following; Bifidobacterium animalis Bifidobacterium breve Bifidobacterium lactis Enterococcus faecium, Lactobacillus acidophilus, and Lactobacillus casei.

Distinguishing Between Prebiotics and Probiotics

You have certainly heard of the term probiotics and that is why you are trying to find the best ones for your dog.

However, not many people have heard of the other term ‘prebiotic’ which is very closely related to probiotics.

Now, what are these Prebiotics? They are fiber sources that are used to feed the bacteria in your dog’s gut.

Unlike probiotics which are live bacteria, prebiotics do not introduce new bacteria to your dog’s system. Good probiotics for dogs will often have prebiotics as the initial food source for a healthy gut.

Benefits of Probiotics for Dogs

We have already highlighted some of the benefits your dog will get by consuming probiotics regularly. In this section, we will look at some of the advantages that your dog will get from probiotic supplements.

Soft dog treats

It is however important to note that only certain strains of probiotics will have specific benefits to your dog.

1.  Controls bad bacteria in the dog’s digestive tract

Your dog just like all other animals may encounter bad microorganisms from outside sources. These unwanted bacteria are responsible for causing several bacterial infections which may be deadly to your dog.

Probiotics for dogs will help to reverse this process by producing fatty acids which hinder the growth of dangerous bacteria in the gut.

2.  Improves digestion

Probiotics will help in breaking down food that your dog has consumed and improve the nutritive benefits.

This will greatly reduce bloating and other stomach-related complications that your pup may have experienced before.

You should carefully select the foods to give your dog for an upset stomach. The right foods will help them to get better faster

3.  Strengthen the immune system

The immunity of your dog is the first line of defense against harmful infections that causes diseases. A weak immune system is deadly because it exposes him to health hazards that can be deadly to him.

Probiotics help in strengthening the immunity of your dog against diseases by producing Cytokines which prompt the stimulation of an adaptive immune system response.

4.  Balances healthy bacteria

Having a balance of healthy bacteria is good for your dog because it will help in controlling the following conditions: Bad breath, diarrhea, bloating, mood, skin, fur, and some allergies.

What is the Best Probiotic for Dogs?

Before making the final purchase decision on the probiotics of your choice, there are a few things you need to keep in mind.

1.  Form of the probiotic

Canine probiotics come in many forms including powder, chews, treats, dog food among others.

When choosing the best form for your dog, we advise that you go for the one that has been minimally processed to ensure the bacterial strain stays effective.

Probiotic Formulation

We also recommend that you choose the one that has single packages which prevent moisture contact with the product.

2.  Multiple strains

Each canine probiotic has different bacteria strains with diverse benefits to your pup. It is recommended that you choose a probiotic with different types of multiple strains.

This will diversify the benefits that your dog will get when consuming the product. You can check the ingredients panel on the probiotic package to check on the bacterial strain available and the benefits they offer to your dog.

3.  The Calories Forming Unit of the product

Colony Forming Units commonly known by its abbreviation CFU refers to the number of bacteria in a count of probiotics. The CFU should be as high as possible, even to 3 billion.

The higher the number means that the probiotic can pass through your dog’s acidic stomach to the gut making him reap all the benefits of the probiotics. Probiotics with a lower amount of CFU are often not beneficial to your dog.

4.  Flavors

By themselves, probiotics do not have an appealing taste that will attract your dog to consume. They are therefore formulated with flavorings that will make it easier for your lovely pup to consume.

Bonding with dog

It is very important that you know the type of flavor that has been added to the probiotics of your choice. We recommend choosing a product that has one source of flavor e.g., liver, chicken, or that which is easier for your dog to digest.

5.  Other Additives

Most probiotics are formulated with other additives which will work towards ensuring your dog gets the best overall experience.

Such include digestive enzymes which are critical in balancing your dog’s gastrointestinal tract.

After buying your chosen probiotics, make sure you store them well in your home. Ideally, the products should be kept in a cool place to allow bacteria to live.

When to Give Your Dog Probiotics

Canine probiotics are beneficial to dogs and can help them out during specific circumstances. These should be seen as dietary supplements that help your dog remain healthy.

If you notice that your canine friend is having issues with his stomach and/or diarrhea, you can add a probiotic diet to relieve their gastrointestinal tract.

If your dog has anxiety or stress, then you can give him appropriate portions of probiotics to manage his situation.

Situations that might stress your dog may vary including vet visits, staying alone at home, or visiting the daycare among others.

If you are planning to change your dog’s diet, then a probiotic supplement will do good to help keep up with his gut health as he adjusts to a new feeding mode.

Most top rated probiotics for dogs are formulated with dog digestive enzymes that help with food transition in dogs.


A probiotic should be used and administered as supplemental feeding only. It might not be the best option to feed your dog on probiotics daily as it may pose unwanted risks to his health. We recommend that you consult your vet on the best time and period to give your dog this supplement.

  1. Thanks, this is very detailed and highly informative!

    Knowing all the pros and cons of these products and taking them to the vet can help people choose the one or two they want.

    Exercise and nutrition and having prebiotic fiber help build up the good bacteria. On top of having the right kind of probiotics as supplements will offer sustainable good health to a dog.

    I usually go for the PetHonesty Allergy Support for my golden retriever, however, it doesn’t suit him anymore. Do you think the Strawfield brand is fine for dogs with allergies?

    Didn’t know that Probiotics can also help reduce dogs’ anxiety and stress. It is good to know.

    • Thanks for your input and for sharing your knowledge. Strawfield probiotics should be good for a dog with allergies and constipation. Let me know if you have anymore questions.

  2. I have read a lot about probiotics for humans and every time I take antibiotics I take probiotics as well to get those gut bacteria back up and healthy. My Golden Retriever just had an antibiotics treatment and I’m looking for a probiotic to give him. I think I will get the NUSENTIA brand, seems good for giving it with antibiotics. Do you agree?

    • Lizzy, I agree with your choice, NUSENTIA is the best probiotic to be taken along antibiotics. I hope your Golden Retriever gets well soon!
